C LEANER FORSHA KlNG-SIEVES.

SPECIFICATION formingpart of Letters Patent No. 606,742, dated July 5,1898. Application filed October 4,1897. smart. 654,060. (No ime.)

To all whom itmayconcern.

Be it known that 1, JOHN E. SEAY, a citizen of the United States,residing at N oblesville, in the county of Hamilton and State ofIndiana, have invented certain-new and useful Improvements in Cleanersfor Shaking- Sieves, of which the following is a speoification. 1 p

The object of; my said invention is to pro- .duce an efficient cleaningand agitating device for that class of sieves (composed generally of twosifting'fabrics stretched upon a frame) such as are used. inshaking-sifters, especially those having a horizontal gyratory motion.

Said invention consists in the combination, with the sieve, of a loosecleaner mounted between the two sifting fabrics and composed, generallyspeaking, of a base, a fibrous and somewhat elastic sweeping materialsecured to the upper side of said base, and a hard smooth (preferablymetallic) bearing-plate secured to the under side of said base, saidcleaner being adapted to move over the surfaces of the sifting fabricsand free them from adhering material, as will be hereinafter moreparticularly described and claimed.

Referring to the accompanying drawings, which are made a part hereof,and on which similar numerals of reference indicate similar parts,Figure l is a top or plan view of the two ends of a sieve of thecharacter with which my improved cleaner is designed'to be employed, thecentral portion (including several sections, according to the length ofthe sieve) being broken away, and portions of the upper siftingfabric'being also broken away, showing thatbelow, with one of myimproved cleaners shown in each section; Fig. 2, a sectional View, on anenlarged scale, as seen from the dotted line 2 2 in Fig. 1; Fig. 3, atop or plan view of one of my improved cleaners, substantially fullsize; Fig. 4, a sectional View of the same on the dotted line at 4 inFig. 3, and Fig. 5 an under side plan View thereof. V

The sieve in itself is not peculiar to my present invention, but will.be briefly described to indicate its character. It is composed ofasuitable frame 1, having intermediate cross -bars 2, dividing itsubstantially into squares,with a comparatively coarse sifting fabric 3over its lower side (which fabric is generally composed of wire-cloth)and a fine sifting fabric 4 stretched over its upper side;(which fabricis generally composed of silk'cloth'.) It will be understood,of course,

that the meshes especially of this latter are very much exaggerated inthe drawings with lines as fine as the meshes of silk cloth, and themeshes of the wire-cloth 3 are also some- .what exaggerated. Thecross-bars 2,by which the sieve is' divided into sections or squares,are preferably rounded somewhat onthe upper side, as shown in Fig. 2,and the rounding sides covered with some soft material o,

such as strips" of cotton flannel, to prevent preferably secured to thebase 6 by small tacks or screws 8, and shoes or bearing-plates 9, whichare preferably cut from thin sheet metal with the ends driven up throughthe base 6 and clenched over, as best shown in Fig. 4. In order to givea proper distance between the surface of the sieve fabric on which thecleaner rests and the base, I prefer to interpose a thin piece 10 ofsome material, such as Wood, by which this result is accomplished.

, I have discovered by practical experiment that these cleaners, whilelight and very inexpensive, have the faculty in operation of traversingthe entire space within which they 'are confined and by their combinedjarring and sweeping action to keep the sieve fabrics entirely free fromadhering material.

Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is-

The combination, with a sieve composed of a frame and a sieve fabricsecured on both its upper and its lower side, of a cleaner mountedloosely between said fabrics to slide on one and brush against theother, said cleaner being composed of a leather base 6, the wool sweep7, and the metal bearing-plate or shoe 9, substantially as set forth.

In witness whereof I have hereunto set my hand and seal, at Noblesville,Indiana, this 24th day of September, A. D. 1897.
